This blog is part of a series around design patterns. This post focuses on the adapter pattern. The adapter pattern is used to enable you to use the functionality defined by a class which is not compatible with the interfaces/architecture of your solution.

Enabling C# 8's nullable references feature often produces a lot of warnings. Avoid the temptation to make some go away by initializing properties to empty strings.

This blog is part of a series around design patterns. This post focuses on the decorator pattern. The decorator pattern is used to dynamically add additional properties to objects in order to extend functionality.

Data Engineers/Developers want to get access to Azure Synapse Analytics as quickly as possible to start designing and creating their data solutions. Being denied access to Synapse Studio can be frustrating and slows matters down. This article will address the "You need permission to access workspace..." error, discuss what causes it, and describe how to fix it.

Azure Synapse Analytics developers need to be assigned a role within Synapse Studio in order to access the GUI. The Azure CLI provides one way of programmatically achieving this, which can be done by any Owner or Contributor of the Azure Synapse Analytics resource.

Despite the subsequent media reporting, the loss of 16,000 Covid-19 test results at Public Health England wasn't caused by Excel. This post argues that a lack of an appropriate risk and mitigation analysis left the process exposed to human error, which ultimately led to the loss of data and inaccurate reporting. It describes a simple process that could have been applied to prevent the error, and how it will help if you're worried about ensuring quality or reducing risk in your own business, technology or data programmes.

At endjin we solve complex problems which cover a huge range of cloud services, data science techniques and industries. The work we do is massively varied and in this there is a huge opportunity. Hear about Carmel's experience in completing her apprenticeship here at endjin, and why you should consider our apprenticeship scheme!

We all get nervous in the run up to a public speaking event. However, there are things we can do which help alleviate some of the pressure. Here are 5 quick tips around preparing for a talk!

There are many different paths into the tech industry, Carmel has been speaking at some local schools about joining the industry from a scientific background. In this post she discusses the crucial tools which science gives you which can help you succeed in tech!

Azure Synapse Link for Cosmos DB is a game-changing piece in the Synapse suite of services - extending the support for SQL on Demand to enable querying over the Cosmos DB Analytical Store. This post explores whether the term 'full stack serverless' should now be extended to cover No-ETL and pay-as-you-query analytics, alongside serverless application architectures.

Serverless data architectures enable leaner data insights and operations. How do you reap the rewards while avoiding the potential pitfalls?

There is a new service in town that promises to transform the way you query the contents of your data lake. Azure Synapse Analytics comes with a new offering called SQL Serverless allowing you to query your data on-demand with no need for pre-provisioned resources.When we heard about the new service we were keen to get involved, so for the last 10 months we've been working with the SQL Serverless product group to provide feedback on the service and to help ensure it meets our customers needs. During this time we've put it through it's paces by implementing a range of real-world use cases. We were particularly interested to see how it stacked up as a replacement for Data Lake Analytics, where to date there has been no clear and easy migration path.

Have you or are you about to invest in Azure Databricks? If so, the new Spark offering in Azure Synapse Analytics is likely to have grabbed your attention and rightly so. Why is Microsoft putting yet another Spark offering on the table and what does it mean for you?

Building a system that solves even just 10% of a problem is a worthwhile endeavour, not just because of the value the 10% delivers but because its mere existence will lower the barrier-to-entry for your colleagues to collaboratively iterate on it - not so much 'Build it and they will come' as 'Build a road and they will come'

A few years ago, I attended a Guardian 1-day Masterclass - Introduction to Data Visualisation. What I did not know then was that it would have a profound effect on how I view design. This blog is a recap of that day and reference points to consider when designing and creating graphics for data visualisation.

GitOps (sometimes known as 'operations by pull request') is most often discussed as being an approach for managing your Kubernetes platform, but in this post I will make the case for how it can benefit a much wider audience.

This post describes the reasons for choosing specific & immutable dependency versions in your software.

Often when building software we need to outsource part of the solution to a third party. Common examples include authentication, payment, and email, but there are many others. When first designing a solution the decision around which provider to use can be difficult to tackle. At endjin we have developed a system for answering the question "which provider should I use?".

I was recently invited on to Microsoft Mechanics to talk about the new on-demand SQL Serverless offering within Azure Synapse. If you have been following along with my previous blog posts you will know that we've been hard at work applying Azure Synapse against real customer workloads. In the video I take you through the service by solving a real-world IoT problem for one of our telco customers.

We use Wardley Mapping as a technique to give us situational awareness in our technical decision making process. We're sharing our Office 365 Templates for PowerPoint and Visio, so that you can make use of them too.

For years we have been building modern cloud data solutions on Azure and helping our customers transform their use of data to drive outcomes. Here are 5 reasons why Azure Synapse Analytics might just be the service that we have been crying out for.

Many API frameworks implement an async HTTP API pattern to address the problem of coordinating the state of long-running operations with external clients. This post looks at how we can use Axios interceptors to simplify and centralise the UI logic required to work with this API pattern.

Making your Power BI reports accessible is crucial, and one important aspect is legibility. If you're using background colours to represent certain categories, then you need any text that's used in conjunction with that background to be as clear as possible. This blog demonstrates how to dynamically select the best font colour to overlay on any chosen background colour.
